Discover the magnetic force of the Earth! Impress your friends with this giant compass, which measures 30 cm in width when you construct it. It's ideal for science projects at school!
HOW IT WORKS: The two magnets of the arm have two points where the magnetic force is stronger. These parts are called poles. The Earth acts like a magnet, too. It's as if there is a giant bar magnet at the center of the Earth, with two magnetic poles near the geographic north and south poles of the Earth. The red poles of the magnets are attracted to the magnetic pole of the Earth, which is located near the north geographic pole. These red poles are called north poles because they point north. The blue poles are attracted to the south magnetic pole of the Earth, which is why they are called south poles. The arm of the compass always rotates to point towards the poles. Most compasses work like the Giant Magnetic Compass. The needle of the compass is magnetized at both ends and indicates direction when attracted by the magnetic force of the Earth.
